I think I should add a qualifier to my earlier statement. If you don't have many users then something like postini maybe the way to go (we actually use it where I work now.about 100 users), but at my previous position it made much more sense to buy a $3000 barracuda for 6000 users than $4 x 12months x 6000 users. The $3000 model that we had processes between 90,000 and 120,000 messages a day with no problems. Even the threshold set to the default of 3 out of 10, and Bayesian filtering not even used, 78% of our messages dropped before hitting the exchange server. Talk about a cheap way to cut load and increase life on a mail server. But again, that would have been a little expensive for 100 users _____ I would almost bet the barracuda will cost you less in time AND labor than others. And it works great!!!
